DS 4.5 is marked as Pending Release now, if you find bugs, report them and most of them should be, hopefully, fixed in a blink. To report bugs you need to register at bugs.daz3d.com.
Regarding limits: Turn Limits Off in the Edit menu (also available as Option menu button on the Parameters tab) works AFAICT on scene saves (last tested on DS 4.0.3) but not on pose presets. Don't know if this is intended or not.

The only way that I have gotten Limits to turn off reliably, is by selecting all the bones and the main figure, and going to Edti/Figure/Limits and turning them off. Originally, I was dealing with the dragon, which the limits on the wings were totally out of proportion to animate them realistically. Then, I was animating a short video using the Genesis character. This method gave me no problems at all when importing motion capture.
